If your multimeter displays a reading above the specified level it is an indication that you will also have to replace the coil of your chainsaw because it is open.
How do you test a chainsaw ignition coil?
Pull the start rope on the chainsaw and watch the end of the plug as you do. If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good. If there is no spark, it means the chainsaw coil will need to be replaced.
What causes ignition coil failure?
The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.
How many ohms should a chainsaw coil have?
As well as this, also attach it to the terminal that connects to the chainsaw’s spark plug. A coil’s secondary resistance range (on average) is from 6 thousand to 10 thousand ohms. However, you need to make use of your manual to confirm the right secondary readings of the chainsaw you own.
How many ohms Should a coil read?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.
How does a chainsaw magneto work?
The magneto creates the electrical charge needed to fire the spark plug, and the spark plug creates the spark inside the combustion chamber to ignite the gasoline (see How Two-stroke Engines Work for details).
How much does it cost to fix an ignition coil?
The average cost for ignition coil replacement is between $209 and $278. Labor costs are estimated between $51 and $64 while parts are priced between $158 and $214. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Can bad coil damage spark plugs?
Can A Bad Coil Pack Ruin A Spark Plug? A faulty ignition coil can cause a misfire, which can also cause the spark plugs to malfunction. The spark plug or plug that was firing the bad coil should always be replaced. By doing this, we will be able to restore the power and fuel economy.
How long do ignition coils last?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
What is the gap between ignition coil and flywheel?
Replacing Ignition Coils or Armatures An ignition armature must be set at a precise distance from the flywheel. Your engine repair manual will provide the proper gap for your engine. Common armature gap ranges are . 006 – .
Why does my Stihl chainsaw not start?
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel will evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.
How do you start a stubborn chainsaw?
Try to start the chainsaw after priming the carburetor. 5. Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
Why am I not getting spark from my coil?
There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. You may have to have a good technician have a look, diagnose and estimate repair. Second link gives detailed instructions for testing and diagnosing coil pack.
What causes multiple ignition coils to fail?
What Causes Multiple Ignition Coils To Fail? In case of repeated coil failures, it may be that the coils are functioning too hard than necessary. It can happen because of high secondary resistance. This increased resistance is usually caused by a damaged or worn-out spark plug or too much gap between the plugs.
